Writing Balance Rule: Keep the left component (the step radical) narrower and slightly elevated compared to the wider, more substantial right component.
Simplification Logic: The traditional form 複 uses 衤 (clothes radical) on the left, referring to lined garments with double layers. The simplified form 复 uses 夂 (step/go) as a phonetic and structural simplification, merging multiple graphic variants.

4. Components

Radical 夂 · Walk slowly / winter radical (walk slowly, trail behind)

Semantic Clue (形旁): 衣 (In the traditional form 複, the clothes radical indicates layers of garments.)

Phonetic Clue (声旁): 复 (original sound: fu)

A walking step (夂) combined with structural lines to represent going back over the same path repeatedly.

  • 夂 step / go
  • 日 sun / enclosed shape
  • 又 again / right hand
5. History
Liushu category: Phono-semantic (形声)

Origin: Originally depicted footsteps walking back and forth to show going back, returning, or doing something over again.

Semantic Evolution: From 'to return' or 'to go back and forth' to 'repeating', 'doubling', and further extending into 'complex' (having multiple layers or parts).

  • In classical Chinese, it frequently meant 'to reply' or 'to report back' because you are going back with an answer.
